Hi there, I'm John Eric Hoffmann dos Santos 👋

👨‍💻 Senior Full Stack Developer | Software Architect | Tech Lead


🇺🇸 About Me (English)

I am a Senior Software Engineer and Tech Lead with over 10 years of experience building highly scalable, mission-critical systems. My background spans from modernizing legacy monolithic applications to designing robust event-driven microservices architectures.

Holding a Bachelor's degree in Computer Science, I bring a strong product-driven mindset (ex-founder) to engineering. I focus on delivering code that generates revenue, scales operations efficiently, and reduces infrastructure costs.

  • 🚀 Current Focus: Event-driven microservices, multi-tenant SaaS architectures, and AI integrations (LLMs, RAG, automated pipelines).
  • 💡 Tech Stack: Go (Fiber/Gin), Node.js, PHP, Python, React (Next.js/Native), PostgreSQL, Redis, RabbitMQ, Docker.
  • 🌍 Global Reach: Delivered custom ERPs, CRMs, and Fintech solutions for clients in the US, UK, Canada, and Portugal.
  • 🧠 Interests: Cloud Architecture (AWS/GCP), AI Agents for business automation, and optimizing CI/CD pipelines in Linux environments.
